Smooth App: The new Open Food Facts mobile app for Android and iPhone

Presentation

• This new mobile application aims to showcase Open Food Facts’s power to a broad range of users through a smooth user experience and sleek user interface. It is a Flutter application by Open Food Facts.
• We pioneered the collaborative scanning app in 2012. With this experimental app, we’re reinventing it from the ground up.

Stable version

• Install it on **Android ** (Google Play, F-Droid or Amazon App Store) or iPhone/iPad.

Beta version

• Google Play offers a Beta version you can join freely. We typically push to beta a couple of days before final release.

Testing version

• Note that an internal development build (Android or **iPhone/iPad ** (App Store) if you’d like to use the results of your PRs quicker.

• Smooth-app is developed in parallel to the openfoodfacts-dart plugin, which provides a high level interface with the Open Food Facts API and openfoodfacts_flutter_lints which provides specific linting
• We also have smooth-app_assets to host assets used by the app (currently the tagline)
• Every new interaction with the API should be implemented in the plugin in order to provide these new features to other developers.
• We support desktop platforms (Linux, macOS and Windows), but only for development

Thanks

The app was initially created by Primael. The new Open Food Facts app (smooth_app) was then made possible thanks to an initial grant by the Mozilla Foundation in February 2020, after Pierre pitched them the idea at FOSDEM. A HUGE THANKS 🧡 In addition to the core role of the community, we also had the support from several Google.org fellows and a ShareIt fellow that helped us eventually release the app in June 2022.
